What color and shape are warning signs on the road?

Warning signs on the road are specifically designed to alert drivers to potential hazards or changes in road conditions. These signs are typically yellow and take the shape of a diamond. The bright yellow color is highly visible, allowing drivers to easily notice them and recognize that they should be cautious. The diamond shape is also distinct and universally understood, indicating that the driver should pay attention to the upcoming situation, such as curves, dips, or other road conditions that may not be immediately visible. This combination of color and shape effectively communicates the warning message and helps to promote safe driving practices.
